Abstract
A keyless entry system has a handle housing and a grip cover defining a door handle grip, a keyless entry pad defining a plurality of keys, each identified with a corresponding symbol, a plurality of sensors in proximity to the keys for detecting an object in the vicinity of the keys, an illumination source to selectively backlight the sensors and symbols, and a light-controlling membrane extending over the keyless entry pad. Entering a keyless entry code into the keyless entry pad by selecting keys in a predetermined sequence enables a latch to be selectively disposed in either a locked condition or an unlocked condition. In ambient light, the light-controlling membrane renders the symbol invisible. When the illumination source backlights the sensor and the symbol, the light-controlling membrane renders the symbol visible.
